METHOD FOR CONTROLLING TRIP EVENT OF INVERTER

摘要

Disclosed herein is a method for controlling a trip event of an inverter by taking into account the temperature of the inverter. The method includes: sensing a change in temperature of the inverter for an overload current measurement time using the temperature sensing circuit; determining an amount of heat emitted from the inverter based on the change in temperature; determining an electrical energy of the inverter consumed for the overload current measurement time; determining a compensation reference time based on the amount of heat and the electrical energy; and comparing the compensation reference time with the overload current measurement time to trip the inverter. As a result, the actual temperature of the inverter measured when the inverter is in operation is reflected, so that the trip event of the inverter can be controlled more accurately.
